Parameters

nSize
[Input] value indicates sample size
pX
[Input] pointer to sample values
SWRes
[Output] structure containing Shapiro_Wilk Normality Test results
iOption

Examples

EX1 

void ocmath_shapiro_wilk_test_ex1()
{
    vector vTestData={ 3.1, 4.2, 2.2, 3, 6 };
    NormTestResults SWRes;
    int nRet = ocmath_shapiro_wilk_test(vTestData.GetSize(), vTestData, &SWRes, 1);  
}
